To all whom it may concern: 7

Be it known that l, Gammon KnnsHAw, a subject 0:1". the King of the United Kingdom of Great Britain and Ireland, and resident or (52 Market street. l Vhitworth, in the county of Lancaster, England, have invented new and useful Improvements in Tension Devices or Yarn- Cleaners for Creels for Use inVVarping or Beaming, of which the following is a specification.

This invention relates to means for supporting; tension disks in creels in which yarn packages are mounted in order that yarn may be warped or beamed.

The object of the invention is to facilitate mounting tension disks beneath the horizontal rails of creels for shelter from falling fluff, dust and the like while insuring that yarn shall be properly subjected. to tension by the disks and facilitating the threading or introduction of yarn between the tension disks whenever there may be occasion so to do.

lVith the said object the invention con sists in supports which enable tension disks,

to be mounted and can themselves be mounted easily and conveniently beneath the horizontal rails of creels and so shelpath between the disks and so be properly subjected to tension thereby and also enable attendants easily to thread or introducethe yarn between the tension disks whenever there may be occasion so to do, and are sa ong, stiff andlight.

In the accompanying drawings, Figures 1 and. 2 are respectively a plan and-side elevation of a tension device and yarn cleaner comprising two disks carried by to this invention.

Fig. 3 is a face view of a tension disk. Fig. at is a detail plan view or a part of a creel. A

Fig. 5 is a detail side view of a part of a creel.

The same letters of reference indicate cor-' responding parts in all'the figures.

In Figs. 1 and 2, a is a support for the metal plate in order to be'made as light as practicable; The disks 6 0 aresimilar -to disks already much used in tension detical parts 7i provided according flanges or" the disk 0 annular weights f may be applied as indicated by illustration of one such weight 7, so that the application or removal of one weight f or more may be made to adjust the pressure, and consequently the drag or tension and cleaning action on yarn passed between the disks b" c as may be requisite or desirable from time to time. The lower disk?) is mounted to turnaround a pin 9 secured in the support a.

According to the conditions of difi'erent cases of use, the lower disk b may be made to bear on the apex of the pin 9 or to bear by a central boss 'or part of its lower surface on thc surface from i For the purpose of and according to this invention the support a is formed with three horizontal parts a a tr in the lowest a of which the pin 9 is secured. The'three horizontal parts a (fa -are at diflierent levels and are shown as connected by ver- The uppermost horizontal parta is intended to be applied against the lower surface of the rail j on which the tension device or yarn cleaner A is to be mounted and has flanges 76 at two sides to stiiten it and a hole Z and communicating slot 722 respectively to allow passage ofthe circularpart 0f a wing nut' and to allow passageot the wings or lateral extensions or the nut and also passage of the bolt 'by which the support a may" be secured to the rail on. which it is to be mounted. 1

If a support a is to be mounted between the flanges of a channeled supporting rail it is preferable that the flanges 7c of the suport a shall be 'ustso far apart as to fit be- P J tween. the flanges of the rail as in thecase illustrated.

with a guide notch 71/ to present its closed end 1n pOS1t101'l to act 'asya gulde' for yarn I andwitha laterally extending or hookq The central horizontal part a is formed making it easy to introduce yarn into the guide notch a. The part a is formed so far below the part a that when the part a is applied to the lower surface of a railin a creel, the arm or hook 0 is so far below the rail that yarn can easily be caught upon and made to pass along the armor hook 0 so as to become guided by the closed end of the guide notch n. The lowest horizontal part a is cut away or shaped so as to alford as little surface as is practicable for the lodgment of fly or dust or other loose material and is formed so far below the part a that the part a is a little below the horizontal surface presented-by the disk 7) to the lower face of the disk 0 The vertical part 2' connecting the horizontal parts a a is provided with a finger ;0 shown for example as secured'to it, which has its upper edge a little below the horizontal surface presented to the disk 0 by the disk 6 and extends around one half of the circumference of the disk I) and so prevents yarn from being passed accidentally beneath the disk 7).

supports according to this invention Figs. 6 and '5 illustrate such supports applied to a a creel with revoluble holdersadapted each to carry three yarn packages with the beginning of the yarn or thread of one connected to the end of the yarn or thread of another so that they may beunwound in succession in the manner aforesaid.

.In the creel shown, 7', j are horizontal rails which may be inclined one to another in pairs placed one over another, which rails" may be furnished with a number of revolubleholdersg for the yarn packages 7", from which the yarn-is tobe led in the. usual way to beams. he The rails j of the creel are made to carry anumber of revoluble holders 9 equal to' the number of yarns intended to be warped I around a stud 2 screwed into the rail j and or beamed at anyone time and'above each holderfig' a tension device; A is mounted by its; support a being secured to the rail above it by means of a bolt to and wing nut'w.

' The. rails- 7' are shown as-o'f-channel section with downwardly directed flanges 3 The revoluble holders 9 are shown as each comprising a three armed plate 2 provided withthree pegs 1 inclined inwardly upward Y from the arms so that their central lines are directed toward the guide notch n of the tension device A above to which yarn is to pass from the yarnpackages 7" on the pegs 1. Each of the plates .2 is mounted to revolve formed with a shank of height greater than the thickness of the plate a so that the holders q can be turned easily.

V f-The supports av are applied to the rails j L 7 so that the parts a arebetween the flanges y of the rails'j and the flanges k of the supports a' fitting against the flanges y'ofthe rails j make it easy to adjust the supports a in position lengthwise of the rails j.

In being applied to or removed from a rail j the support of a tension device ,A is made to present the hole Z and slot m to and passed over the nut m on the bolt to for securing it and when the slot m is made to receive the bolt to the. nutra may be used to fasten the support a. v

The supports a of all the tension devices A being alike it is to be noted that as seen by a person between the two sides of a creel and looking toward the apex of the creel or toward the beaming frame 85 the supports a on the rails j to the right hand are disposed so as to have the arms 0 and the openings of the guide notches n directed away from the beaming frame 8 and those on the rails j to the left hand are disposed so as to have the arms or hooks'o and the openings of the ing yarn into the guide notches a whether By way of example of the apphcation of the tension devices A to be threaded are to the right hand or the left hand.

V The disposition of the tension devices A on the rails j at opposite sides of the creel requires the guide rods t at opposite sides of the creel to be mounted as is indicated in the drawing so that. those 'on the right as seen from within the creel and looking toward the beaming frame to are on the left of yarn passing to them and those on the left of the creel are to the right of yarn passing to them in'order that the yarns passing to them respectivelymay pass around the sleeves cl of the disks '6.

, Further since the tension devices A are.

underneath the rails j on which they are mounted and more especially in the'use of rails of channel section as shown, thetension devices A, and'more particularly those below others-"are effectively sheltered. from falling dust; fluff and the like, so that the deposit ofdust fluff and the like in masses liable to become attached to the yarn passed through the tension device is obviated.

From the foregoing it will be seen that in a support for tension disks provided according to this invention there are pIOVlClGCl three horizontal parts connected together.

The upper horizontal part serves to bear position and is preferably furnished with lateral flanges for stiffness. The' second horizontal-part has a notch forminga guide f for yarnandpreferably a lateral extension or finger. with which yarn. may be engaged so as tobe passed into the notch and serves to guide: yarn to the tension disks. The thlrd and lowest horizontal part is adapted to carry the tension disks. The holder is also provided with a curved finger or guard extending around part of the circumference of the tension disks to insure that yarn shall pass properly between them. Most advantageously as in the case illustrated the support is stamped or shaped from metal plate so as to be as light as is practicable.

Formation of the supports in the manner described, especially when the supports are made to tit between the flanges of channeled rails, makes it a very easy and convenient operation to mount and to adjust tension devices on the lower sides of the rails of crecls while making it quite easy for yarn to be introduced into them and insures that yarn shall pass through the tension devices in the proper path so as to be subjected to tension and cleaned thereby.

Supports formed according to this invention are particularly advantageous for supporting tension disks in creels of thekind in which yarn packages are mounted in groups with the beginning of the thread or yarn of one connected to the end of the thread or yarn from another, so that yarn may be drawn oit these successively with out stoppage of the warping or beaming and while the warping or beaming continues uninterruptedly fresh yarn packages can be applied to take the place of those from which yarn has been drawn off.
